This was for vfs.mountroot.timeout .  

There needs to be better documentation.  I have already searched for too many needles in the haystack and lost a lot of time that way.

I could type "show" at loader prompt, but figure only a small chance of finding everything, output may be sketchy.

So I still don't know whether it should be seconds or milliseconds.

Where did you find it in the source tree?  I made another search, unsuccessful, for the needle in the haystack.
